Revert "PCI: PCIE ASPM support"

This reverts commit 6c723d5. It caused build errors on non-x86 platforms, config file confusion, and even some boot errors on some x86-64 boxes. All around, not quite ready for prime-time :( Cc: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
